Subject: CVE-2018-1297: Apache JMeter uses an unsecure RMI connection in
Distributed mode
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected: JMeter 2.X, 3.X
Description [0]:
When using Distributed Test only (RMI based), jmeter uses an unsecured RMI
connection.
This could allow an attacker to get Access to JMeterEngine and send
unauthorized code.
This only affect tests running in Distributed mode.
Mitigation:
* Users must use last version of Java 8 or Java 9
* Users must upgrade to last JMeter 4.0 version and use the default /
enabled authenticated SSL RMI connection.
Besides, we remind users that in distributed mode, JMeter makes an
Architectural assumption
that it is operating on a 'safe' network. i.e. everyone with access to the
network is considered trusted.
This typically means a dedicated VPN or similar is being used.
Example:
* Start JMeter server using either jmeter-server or jmeter -s
* If JMeter listens on unsecure rmi connection (ie you can connect to it
using a JMeter client), you are vulnerable
